ABSTRACT:
A work piece1mounted on a movable table22is rotated while adjusting cutting depths of a grinding wheel23by means of feed motor so as to perform cylindrical grinding. During the cylindrical grinding, a thermocouple42is pushed to and caused to contact the rotating cylindrical grinding surface1aof the work piece1at a constant pressure and thermoelectromotive force generated by the thermocouple42is measured. Surface roughness data corresponding to the measured thermoelectromotive force are obtained on the basis of the thermoelectromotive data obtained by the measurement and correlation between thermoelectromotive force and surface roughness concerning a known standard surface previously obtained and memorized. The surface roughness data are output and displayed on a display section. Therefore, an in-process measurement of surface state of the work piece1can be performed, while the machining such as cylindrical grinding is being carried out.
